What are Conditions needed to cause water to diffuse in cell?

Answer 1

The primary drivinf force for diffusion is a concentration gradient. There has to be an abundance of molecules at one region and a scarcity of molecules at another. This differential distribution of molecules where one region has more than the other is called a concentration gradient. In the presence of this gradient, diffusion occurs without the expenditure of energy. In cells, diffusion can occur through the cell membrane. Water molecules move into or out of the cell depending on where there are more water molecules. If there is more water outside the cell, water molecules move in and vice versa.

Answer 2

In general, water diffuses across a cell membrane through a process known as osmosis. This occurs when there is a difference in solute concentration between the inside and outside of the cell. Water will move from an area of higher water concentration (hypotonic solution) to an area of lower water concentration (hypertonic solution) to equalize the solute concentrations on both sides of the membrane.
